PHP denying use of short hand “<?”

问题:

I just installed php 5.3.0 and it won't run php scripts utilizing short open tags like <?, only <?PHP.

回答1:

You need to update your php.ini file.

Set short_open_tag = 1

See the PHP Manual

回答2:

That's because it's simply a bad practice. I suggest re-converting all your scripts to use <?php. If you're lazy, you can use a find and replace, if you have access to powerful command lines like bash you can use sed to do this for you.

you need to

ini_set("short_open_tag", 1)

or adjust your systems php.ini file.
